347 Stainless Steel Plate

What is Stainless Steel 347 Sheet?

Colombium stabilized grade 347 is an austenitic stainless steel alloy. A major advantage grade SUS 347 offers over many other austenitic alloys such as grade 304 and 316 is its excellent resistance to intergranular corrosion at elevated temperatures

For instance, when ASTM A240 347 SS plates have been exposed to a temperature range from 800 to 1500°F, which is referred to as the chromium carbide precipitation range, these plates exhibit excellent performance. The mechanical properties of SA 240 Gr 347 SS coils, strips and plates are best suited for elevated temperature use, particularly due to a high creep resistance. The yield strength of ASTM A240 Type 347 specified plates is about 515 MPA, whereas the alloys melting point ranges in between temperatures 1398°C to about 1446°C.

Usually, finishes are known to add value or improve certain lacking areas of the alloy it is being done on. The SS Werkstoff No 1.4550 strips, plates, coils and sheets can be finished with the following finishes i.e. - Hot rolled plate, Cold rolled sheet, matt, matt PVC, 2B, 2D, both side polish, NO(8), hairline, textured, Satin Met with Plastic, brushed, oil based wet polish, No. 4, No 5, No. 8, HR, SB. The standard thickness of the AISI 347 UNS S34700 shim stock ranges between 4.8mm to 101.6mm.

What is ASTM A240 Grade 347 Plate?

Plates, coils, sheets, strips produced from chromium based alloys, which in this case is alloy 347 Stainless Steel are enveloped by the ASTM A240 specification. Similar to most ASTM specifications, the two main aspects covered and specified here include the chemistry of the alloy as well as the mechanical property requirements of the components produced in that same alloy.
